Decode Base64 to text or encode text to Base64. Paste into the top box, read the result below, and flip the direction with one click. Handles Unicode correctly, reads URL-safe Base64, and shows binary payloads as a hex dump you can download.
Convert a color between HEX, RGB, HSL, HSV, HWB, CMYK, OKLCH and OKLAB. Type into any field and the others update as you go, or pick the color visually. Reads CSS color syntax and keeps alpha where the format supports it.
Convert between px, rem, em, percent, pt and viewport units with a configurable root font size. Type into any field and the others update as you go, set the parent font size for em math, and read a conversion table for common sizes.
Turn a series of images into a video. Drop in your frames, reorder them, set the frame rate and resolution, and encode the result as MP4 or WebM, ready to play anywhere.
Convert an animated GIF into an MP4 or WebM video. Videos are far smaller than GIFs and play everywhere, so this is the quickest way to make a heavy GIF shareable.
Escape text into HTML entities or decode entities back to plain text. Choose named or numeric entities, escape only the unsafe characters or everything outside ASCII, and read the result live.
Convert images between JPEG, PNG, WebP and AVIF. Drop in as many as you like, pick a format, and dial in the quality for the lossy ones. When you convert to JPEG, choose the colour that fills any transparency. Live previews, download one or all at once.
Convert images into data URIs you can paste straight into CSS or HTML. Shows the encoded size next to the original, wraps the result as a CSS background or img tag if you want, and handles whole batches at once. Also decodes a pasted data URI back into a file.
Read the text out of a screenshot, photo or scan with OCR. Pick the language, watch the recognition progress, review the result with per-word confidence, and copy or download the extracted text.
Turn photos and images into a single PDF. Drop in JPEG, PNG or WebP files, reorder them, pick the page size, orientation and margins, and choose whether each image fills the page or keeps its own size.
Paste JSON and get matching TypeScript types, with interfaces or type aliases, optional readonly fields and comments showing example values detected in your data. Nested objects become their own named types.
Paste anything that looks encoded and this tool works out what was used and undoes it, layer by layer. The whole BaseXX family from Base16 to Base85, binary, URL escapes, HTML entities, ROT13 and gzip, Brotli or Zstandard compression are detected in any combination, and every step of the chain is reported.
Translate text to Morse code and Morse back to text, with a reference table of every letter, digit and punctuation mark. Play any result as sound with adjustable speed and tone.
Convert numbers between binary, octal, decimal, hexadecimal and any base up to 36. Type into any field and the others update as you go. Handles huge integers without losing precision and accepts 0x, 0b and 0o prefixes.
Render every page of a PDF as an image. Choose PNG or JPEG, set the resolution, pick single pages or a range, then download pages one by one or all at once as a zip.
Convert between scientific notation and full numbers as you type. Reads 1.23e5, 1.23 × 10^5 and plain numbers, shows the value written out, in normalized scientific notation and in engineering notation, and can round to any number of significant digits.

Escape or unescape a string for JSON, JavaScript, regex, shell, SQL, CSV, XML and more. Paste text, pick the target format and copy the result, in either direction.
Convert subtitles between SRT and VTT, shift their timing forward or backward, and fix frame rate drift to sync out-of-sync captions. Preview the parsed cues, catch format errors, and download the converted file.

Convert Unix timestamps in seconds, milliseconds, microseconds or nanoseconds to readable dates in your local time, UTC or any timezone, and turn any date back into a timestamp. Shows the live current timestamp and relative time.
Encode text for use in URLs or decode percent-escaped strings back to readable text. Choose component, full-URL or form encoding, unwrap double-encoded strings, and break a URL into its parts with every query parameter decoded.
Convert videos between MP4, WebM, MKV and MOV. Drop in one or more files, pick the target format and quality, follow the encoding progress, and download the results one by one or all at once.
Extract still frames from a video. Grab every frame, every Nth one or one per second, or step through and pick single frames by hand. Choose PNG, JPEG or WebP for the output and download everything as a zip.
Turn a video clip into an animated GIF. Pick the exact section on a timeline, set the frame rate, size and loop behavior, and fine-tune the palette for a small file that still looks good.
